GRIP FOR CABLE RAILWAYS.

LEPECIFICATIQN forming part of Letters Patent No. 325,633, datedSeptember 1, 1885.

Application filed June 16,1855. (No model.)

T 0 all whom, it may concern.-

Be it known that I, CHARLns SoHoLz, a subject of the Emperor of Germany,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Cable Railways, of whichthei'ollowing isa specification, reference being had therein to theaccompanying drawings.

My invention relates to certain improvements in cable-grips.

The object of the invention is principally to render certain thedisengagement of the grip and cable when the change from one cable toanother is necessary; and to the accomplishment of that end it consistsof certain novel devices and combination of devices, as will bedescribed and claimed.

Reference will be made to the accompanying drawings, in which Figure lis a side elevation ofthe grip; Fig. 2, a section on line 1 l; Fig. 3, asection on line 2 2, and Figs. 4 and 5 details of parts.

Like letters refer to like parts in each view.

A represents the flooring of the ear, and B one of the beams thereof,there being a suitable opening in the liooring for the operation ofcertain of the parts.

Mortised into beam B is a vertical piece, C, which at its lower end issecured to the stationary part D of the grip proper. Suitably situatedat a point slightly above this part D is a bar, E, to the opposite endsof which uprights F are secured. These up rights pass up throughopenings formed in beam B, and areconnccted at their upper ends by acurved crosspiece, G.

At or about the center of piece G there is secured an arm, H, vwhich atits lower end is pivoted to one end of an arm, H', the opposite end ofthe latter arm being secured to a bolt, K, passed through beam B.

Secured to the opposite end of bolt K is a lever, L, carrying a dog, If,adapted to mesh with a segmental rack, M, mounted upon beam B. By thisarrangement of parts it will be seen that, supposing the lever to be inthe position shown in full lines, Fig'. 1, if it is turned so that thedog will engage with the rack at its opposite side or end, the arms HIlwill operate to force cross-piece G, uprights F, and cross-bar Eupwardly or toward stationary part D of the grip.

Secured to bar E are two posts, M', which extend downwardly and areconnected with the movable part D of the grip, connection being thusmade to raise said part D with bar E. Two sets of spring-arms, N, arealso mounted upon part D', said arms being provided on their upper endswith enlarged heads adapted to rest upon bar E, the length of such armsbeing sufficient to allow this.

At a point in the track-groove slightly in advance of the point whereone cable is to be left and another taken up there is a wedgeshapedpiece, O, inserted. The heads of spring-arms N move in the track-groove,and as they strike thispiece O they are forced .from their hold on batE, and the lower part of the grip allowed to fall to the position itoccupied before lbeing raised through themedium of the lever and theintermediate connections described.

UprightsParesituated beside those marked F, said uprights resting uponbar E, and connccted at their upper ends by a curved crossbar, Q, saidbar occupying a position directly above the bar G.

An arm, R, is pivoted to crossbar Q, as at a, Fig. l, and its long endis provided with a handle or stud, S. By raising the long end of thisarm to the position shown in dotted lines, Fig. l, its short end presseson bar G, and serves to raise bar Q and its uprights, as indicated.

At a point near the lower end oi' each upright P there is provided astud, T, resting under the head of an upright, V, said upright passingup through openings in bar E, and resting at their lower ends upon themovable part D' of the grip. At the lower end of each there is providedan enlargement,` c. These nprights are raised by the connectionsdescribed, and as they are raised their heads c raise the cable from thegrip and leave the car entirely free. After the spring-arms have beenreleased from their hold on bar E it will be understood that by raisingthe movable part of the grip they may be carried back to their originalposition.

The grip proper consists of two bars, XV, pivotcd in parts D D by armsX, the arbors IOO of which are provided with springs d, adapted to holdthe bars in the position shown in Fig. l, but at the same time allow ofa certain give to such hars when the cable is seized to prevent a suddenjar. Each bar W is cut away slightly at points e, each cut-away portionof one bar being in a line with a corresponding projection on the other,the cable being by this arrangement firmly seized and held.

Vhat I claim is- 1. The combination, with a two-part grip and mechanismfor operating the same, of spring-arms to hold the parts together, andsuitable mechanism for releasing such arms when desired.

2. The combination, witha twopart grip and mechanism 'for operating thesame, of

spring-arms secured to the movable part of the grip, and provided withenlarged heads adapted to rest upon a cross-bar, and a wedge located inthe track-groove, as set forth.

3. The combination, with suit-able operating mechanism, of a gripconsisting of two frames, each provided with a longitudinal bar hungupon suitable arms, as set forth. y

4. The combination, with suitable operating mechanism, of a gripconsisting of two frames, each provided with a notched longitudinal barhung upon suitable arms, around the arbors of which suitable springs arepassed, as set forth.

'In testimony whereof I affix my signature in presence of two witnesses.
